CALENDAR-CLOCK.

Specification of Letters Patent.

Patented Nov. 14, 1911.

Application filed September 7, 1910. Serial No. 580,894.

To all whom it may concern:

Be it known that I, WILLIAM S. OVERLIN, a citizen of the United States,residing at 1566 Virginia street, Portland, county of Multnomah, andState of Oregon, have invented a new and useful Improvement inCalendar-Clocks, of which the following is a specification.

rlhe present invention consists of a clock adapted for use es ecially inoffices, banks, public places, or t e home, and comprising a calendarautomatically operable once in twenty-four hours to present to view inclearly visible shape, the day of the week, month and year, or similarindicia.

In carrying out the invention, it is contemplated to associate with aclock of any conventional type, a suitable motor, and a calendarconsisting preferably of a continuous tape or strip having printedthereon in large type, the days of the year in consecutive order.

Peculiar controlling mechanism is em;- ployed for permitting operationof the calendar motor at a predetermined time, preferably at twelveoclock at night, to advance the calendar strip or tape to present at avision opening, a new date, the operation of the motor beingautomatically controlled by the clock motor. Coacting with the calendarmotor is a special form of controlling device for automatically stoppingthe calendar motor, the latter forming an essential feature of thepresent invention.

For a full understanding of the present invention, reference is to behad to the following` description and to the accompanying drawings, inwhich- Figure 1 is a sectional view of a clock, showing a member of theclock motor, the calendar motor and the operative connection between thecalendar and said motor; Fig. 2 is a view in elevation showing thecalendar motor and cont-rolling mechanism therefor, the calendar tape orstrip being diagrammatically illustrated in connection with the guidemeans therefor; Fig. 3 is a fragmentary view showing more clearly detailparts of the invention; Fig. 4 is a perspective view of the starting andstopping lever, the detent carried thereby and the tripping lever.

Throughout the following detail description and on the several figuresof the drawings, similar parts are referred to by like referencecharacters.

Specifically describing the invention, 1 denotes the winding shaft, and2 the spring of the calendar motor; 3 is a gear on the shaft 1 whichmeshes with the pinion 5 of the gear 6 on a counter shaft 4, the gear 6meshing with a pinion 7 on a shaft 8 and' the latter having a gear 9meshing with a pinion 10 on a shaft 11. A gear 12 of the shaft 11 mesheswith the pinion 13 of a shaft 13Zt having the fan governor 14.

A'sprocket chain 16 connects the sprockets on the shafts 4 and 15, t-helatter shaftcar rying a drum 17 about which a calendar comprising astrip or continuous tape 18 is adapted to wind. The term strip or tapeas used in connection with the calendar aforesaid is designed primarilyas meaning, in a broad sense, a body of a suitable size to carry theindi-cia of a calendar, whether such body is actually a strip or otherequivalent part. The calendar strip or tape 18 may have any suitableindicia thereon, that illustrated being the name of the month, the dayof the week and the number of the day of the month, the latter being inlarge print so as to be readily visible through a suitable visionopening provided in the clock. The date or calendar strip 18 isinitially carried by a drum 21 and passes around guide rollers 19 and 20to the drum 17 above mentioned, unwinding from the drum 21 and windingaround the drum 17 in the ordinary operation of the machine.

Between the guide rollers 19 and 20 are arranged guide means comprisingclosely spaced plates 22 and 22EL adapted to receive therebetween alongitudinal edge portion of the date strip 18, holding the embracedportion of the strip rigid when `guiding the same. The clock motor withwhich the invention may be associated comprises the operat-ingwheel 23having a laterally projecting pin 24, said wheel 23 being connected upwith the gearing of the clock motor, not' shown, so that the wheel 23makes a complete revolution once in 24 hours. The pin 24 is adapted toengage the adjacent end of a tripping device consisting of the tripping`lever 25 pivoted between its ends at 26, the other end of the lever 25having a weight 27 thereon.

The date strip 18 is formed in its length with a plurality of notchedout portions 18a, one being provided for each date space of thecalendar. The notched out portions 18aL of the calendar strip 18 arepreferably located at one edge of the same and perform a peculiarfunction. Adjacent to the plates 22 and 22 is a bracket 3&1 on which ismount-- ed a shaft 37 having a controller arm 36 at one end and alifting arm 37'nl at its other end, the latter being adapted to beraised by means of a coiled spring 35 connected thereto. A lifting rod38 is attached at its lower end to the free extremity of the lift-- ingarm 37a and the upper end of the lifting rod 38 is loosely secured to alateral projection on the lower arm of a bell crank detent 28 pivoted at29 to a releasing lever 30. The movement of the detent 28 on the lever30 is slight, being limited by spaced projections 28 extending from t-helever 30 on opposite sides of the lower arm of the detent. The lever 3()is pivoted at 31 to the frame of the calendar motor and is provided witha friction shoe t() movable into and out of engagement with a frictionwheel L11 controlling the operation of said motor. Normally a spring 32connected wit-h the lever 30 holds the latter at the upper limit of itsmovement with the shoe 40 engaging the friction wheel 11 to cause thecalendar motor to remain inactive. The detent 28 is so arranged that itsvertical arm is movable so as to engage beneath a projection 33 on themotor frame, and normally the end of the tripping lever 25 opposite thewheel 23 rests on the starting and stopping lever 30.

A lateral projection 36 at the outer end of the controller arm 36 of theshaft 37 is adapted to ride over` the upper curved edges of the guideplates 22 and 22a in engagement with the notched portions 18a andadjacent to the longitudinal edge portion of the calendar strip 18, thenotched portions forming cams coperating with the controller arm 36 in amanner to now be described. The projection 36 bears edgewise againstvthe calendar strip, and t-he buckling of the latter under the pressureof the member 36 is prevented effectively by the immediate contact ofthe guid-e plates 22 and 22EL with the strip on opposite sides thereof.

A small spring 39 connects the lower arm of the detent 28 to the lever30 and has a tendency to force the vertical arm of the detent outwardlybeneath the projection 33.

In the operation of the present invention, assuming that the movement ofthe wheel 23 is properly timed, at twelve oclock at night?, or otherpredetermined time, the pin 211 of the wheel engages the lever 25 so asto raise the weighted end of the lever. As soon as the pin 24 isdisengaged from the lever 25, the weighted end of said lever, which haspreviously been lifted, is permitted to drop, thus imparting a slightdownward movement to the lever 30 suflicient to disengage the frictionshoe l() from the friction wheel 41 and permit the calendar motor tostart its operation. rlhe tension of the spring 32 is sufficient tobring the lever 30 to its original position with the shoe L10 inengagement with the wheel 11, but this is prevented by the engagement ofthe vertical arm of the detent 28 with the projection 33, as shown indotted lines in Fig. 2. a

l/Vhen the calendar strip 18 is not in motion, the projection 36 of thecontroller arm 36 is at the deepest portion of one of the edge notches18a of said strip. The .movement of the strip 18 caused by starting ofits motor gradually forces the proj ect-ion 36 outwardly, therebypositively moving the rod 38 downwardly, said rod thus holding the lever30 away from the wheel 411 through the connection of the rod to thedetent 28. `While the projection 36 rides on the adjacent straight edgeof the strip, the motor will continue to operate the calendar until theprojection 36 is opposite the top portion of the next notch 18a in thecalendar strip, whereupon the movement of the controller arm 36 inwardlytoward the middle portion of the strip is caused by the spring 35, thusrelieving the pull on the rod 38. The loose connection of the rod 38with the detent 28 then permits the lever 30 to be raised by the spring32 and the friction shoe 10 to be engaged wit-h the wheel 11, instantlystopping the motor. When the outward rocking movement of the controllerarm 36 holds the lever 30 down, the tendency of the rod 38 is to exert apull on the horizontal arm ofthe detent 28 sufficient to normally holdthe vertical arm out of engagement with the projection 33. The plates 22and 22EL stiften or render the strip 18 'taut while engaging theprojection 36.

Having thus described the invention, what is claimed as new is:

1. In means of the class described, the combination of a motor, acalendar comprising a strip movable by said motor, means normallypreventing operation of said motor, mechanism for initially releasingthe motor, and controlling means coperating with the releasing mechanismcomprising a controller arm arranged in the path of movement of thecalendar strip, said strip having a cam portion leading to one of itsedges and adapted to engage the controller arm to move the latter intooperative contact with said edge whereby to maintain the operation ofthe motor a predetermined length of time.

2. In means of the class described, the combination of a motor, acalendar comprising a strip having suitable indicia thereon and operablyconnected with the motor, a

releasing lever for the motor, a project-ion adjacent to said lever, adetent carried by the lever, means for normally holding the lever in aposition preventing operation of the motor, means controlled by thecalendar strip and connected with the detent aforesaid to hold the leverin released position, means for initially actuating the lever, and meansfor causing engagement of the detent beneath the projection when thelever is initially actuated.

8. In means of the class described, the combination of a motor, acalendar connected therewith for operation thereby, a releasing leverfor the motor, a tripping member for initially actuating said lever topermitthe motor to operate, a projection adjacent to said lever, adetent carried by the lever to engage the projection when the lever isinitially actuated, and means operable by contact with the calendar inthe movement of the latter connected with the detent of the lever, tohold the latter in released position after initial movement of thelever.

4. In means of the class described, the combination of a motor, acalendar connected therewith for operation thereby, a releasing leverfor the motor, a tripping member for initially releasing the motor, aprojection adjacent to said lever, a detent carried by the lever toengage the projection when the lever is initially released, and meansoperable by contact with the calendar in the movement of the latterconnected with the detent of the lever to hold the latter in releasedposition, after initial movement of the lever, a spring Jfor normallyholding the lever in a position preventing operation of the motor, andspring means connected with the calendar operated member for moving thelatter into a position permitting the releasing lever to stop theoperation of the motor.

5. In combination, a calendar strip, a motor for moving said strip, acontrolling member for governing the operation of the motor, means forholding the controlling member in a position in which it bears againstthe strip edgewise of the latter, means coacting with the controllingmember for releasing and stopping the motor, and means for preventingbuckling of the calendar strip under normal pressure of the controllingmember thereagainst.

In testimony that I claim the foregoing as my own, I hereunto attach mysignature in the presence of two witnesses.
